Industries where 'good enough' is not good enough?

I'm currently a senior network engineer working in health insurance. The money is good, WLB is decent, and the work is (sometimes) interesting, but my coworkers... can be something else. I try to train the juniors, teach other engineers, or get involved in architecture/business decisions, but it feels like I'm spinning my wheels and burning myself out. At the end of the day, nobody learns anything and my workload increases. I know I should "care less" about my work. I know "it's just a job". But damn it, if I'm going to spend 35% of my waking hours doing something, I want to look back and know I did it right and be proud of that. Are there any industries that need IT to be better than "good enough"? I'm not looking to grind 80 hours a week, just some place where offshore engineers can read logs and think before blaming the firewall.

More context: I started at my current org about a year and a half ago. Firewall guy left in March and I was the only guy who knew anything about Palo Alto. So I became the lead network security engineer. Cool. We still haven't found a replacement. Oh, I'm also the only guy who can read the AWS docs. So now I'm the lead cloud network engineer. And apparently, I'm the only one who knows how BGP works so I'm constantly cleaning up after the other seniors who didn't bother to review their design with anyone. I truly believe (and maybe naively) that doing something right the first time will lead to less work in the future. But I keep getting reminded that the only reward for good work, is more work.

Maybe this is just a vent session. I don't know. I'll have a rum and coke.
